Taupānga
Ko te Antixoidant 245 he momo antioxidant phenolic asymmetric tino whai hua, a ko ona ahuatanga motuhake ko te antioxidation tino pai, te iti o te wariu, te aukati ki te tae o te waikura, te whai hua nui ki te antioxidant kaiawhina (penei i te monothioester me te phosphite ester), me te tuku hua huarere pai. ātete ka whakamahia ki te pūmau marama. Ko te Antioxidant 245 te nuinga o te wa e whakamahia ana hei whakamaarama mo te wa roa mo te styrene polymer penei i te HIPS, ABS, MBS, me nga miihini miihini penei i te POM me te PA, i te mea ka mahi ano hei aukati mutunga o te mekameka i roto i te polymerization PVC. I tua atu, kaore he painga o te hua ki nga tauhohenga polymer. Ina whakamahia mo te HIPS me te PVC, ka taea te whakauru ki roto i nga monomers i mua i te polymerization.
